@o L35 whom it manson/caen:

Be it knownthat isnnxanosa iii-snsic-KLB, a citizen ofthe United-States, rssidfing at Indianapolis, in the oo untyof Marion g and State oflnd'iana, have inyented certain new and ,useful Improvements in Gas-Enf. ginas; and -Il dodeciare the following to 'be a` full, clear, and exact" description of the invention ,such as will enable othersskilledin the' 'ro art towh'ich it appertains tomake and" use the saine, reference being had tothe accom panying drawings, and to theletters 'and iig-l ures of reference-marked thereon, which form a part of this specification.A j This invention relates to explosive-engines ih which a mixture of gas and atmospheric air isy employed as a means 4of propulsion; and it consists in the novel' devices and combination and arrangement .thereof whereby zo the mixture is eected, admitted, controlled,

exploded, and exhausted, and in the novel f form andarrangement of .chambers-embraced in the cylinder-head, as will be more lfully described hereinafter, and claimed. y a 5 My object is to generally improve the details of construction of gas-engines, particu-j '.larly of that class which". are designed to be .used in a limited space and upon Vunstable foundations and which shall be composed oi 3o but few. and simple parts ina compact form, the whole adapted to operate with the least jarring or unsteadiness, and this is fully attained in my in vention,wl1i`ch is, furthermore, cheaply constructed and is durable and eco- 35 nomical in use. n 1

Referring to the drawings, Figure 1 repre-` sente acentral vertical sectional view on the line X X of Fig. 2; Fig. 2, a rear elevation; Eig. 3, a side elevationyiig; 4, a side view of 4o the cylinder and a vertical section of explof 'sion-chest, taken on the line Y' of Fig. 2'; Fig.5,a central sectional view taken on a horizontal line throughthel cylinder and eip1osionchest; Fig. 6, a side view of the cyl- 45 inder,'showing a fragmenti-n section andY a vertical section of explosion-chest, taken on thefline vZ of Fig. 2; Fig. T, a central sectional view of the igniter, showing details of and exhaust-valve. lFigs. 9, 10, 11, and l2 are detail ,views of parts of Fig. 8, and Fig. 13 is a vertical central sectional view of# he coin-A bined governonvalve andlmining-cimmber.

The details of construction embody parte which separatelyv are familiar to mechanics and ltherefore require no' minute description as' to material shape or proportion; but stress is iaid herein upon the advantageous combinationof such parts.

The cylinder A'is of the usuai type, having a head a at one end and the opposite end open and is provided witha .water-space d.. -The cylinder, together with the base-fianges B, forms: the support for the wholemachine, the anges,'frame D, and arms D being preferably cast integrally4` 'with -the cylinder. The framehas suitable journal-boxes,n which the main shaft"E is mounted transversely above the cylinder and at a low elevation to economize space. tached to or forged in the main shaft, andthe latter carries suitable balance-wheels J J, to one`o which a belt-.pulley K is attached, or othersuitable means may be employed for transmitting power. 1 i i Alrocking arm or lever Gis suitably jour naled at or near its center' at the enter ends of the arms D' 'for' transmittingA the power from the piston -O to the cranks and main shaft in connection with the connecting-rods H and I. The length of the rocking 'arm in relation to the strokefof the piston is important, the greatest .length practically being the most advantageous. The point of suspension is designed to be suciently removed above the center of the cylinder toprovide for a pro portionately long radius for the lower end o1 the lever, vand the latter iscurved intowardthe cylinder, so that the point at which it isl `pivoted to `the connecting -rod is approximately on' the center line of the cylinder when the piston is taking the effect of the explosion The upper end of the lever is also long enough to provide for a comparatively longV radius in its travel compared to the throwof the crank, the advantage being greatest when its upper end reaches a level-of the crank-pin when the -f construction; Fig'. 8, a central sectional view gerefI the mechanism for operating Ythe ignite? i Twin cranks F F are` at'- latterstands at its upward limit-#that on its V qua rter. This arrangement 'provides of-said cylinder, the means for operating said i gniter and said exhanst-valve, and the inletvalve situate at the top of said explosion-Iv chest, substantially as shown and described.

2. In a'gas-engine, the combination of the horizontal cylinder,- the supporting frame above the cylinder, the main shaft mounted transversely above the cylinder, the gearwheel carried'by the main shaft, the stud secnred to the side of the frame and parallel to the inain shaft, the sleeve revoluble on said stud, the gear-Wheel secured to said sleeve and meshing with the gear-Wheel on the main shaft, the hub adjustably secured to said `sleeve and adapted to carry the igniter-caln with the clutch whereby the4 and provided igniter-cam is driven but permitting the same to be reversed, the igniter-cam loose on said hub and engaged by said clutch whereby it is driven, the trip-lever' engaged with and operated by said cam and adapted to and operating an igniter-stem, substantially as shown and described` 3. In ages-engine, the combination of a horizontal cylinder having the frame thereon,

a main shaft mounted transversely above the cylinder, a gear-wheel carried by the main shaft, a stud secured to the side of the frame and parallel to the .main shaft, a sleeve revoluble on the stud, a gearqvheel secured to the sleeve and meshing with the gear-wheel on the main shaft, an exhaust-valve cam secured to the sleeve, a bell-crank level' snit-- ably supported and adapted to engage with and operating the stem of an exhaust-valve, a h ub adj ustably secu red to the said sleeve and adapted to carry an igniter-cain and provided Y with a clutch whereby to .drive an igniter-cam in one direction but permitting its rotation in an opposite direction, an igniter-cam loose on the huband engaged by the clutch whereby Ait is driven, a trip-lever engaged' with and Operated by the. igniter-cam and adapted to and operating an igniter-stem, substantially as shown and described. v

4. In a gas-engine, the combination of the horizontal cylinder, the frame thereon, theighiter having the stem working at the slde of the frame and parallel to the'cylnder and provided with the rateifetteeth, the main shaft, the gear-wheelt-hereon, the stud secured to the side of the frame, the sleeve loose upon the stud and having the gear-wheel secured thereto and, meshing with the gearwheel on said main shaft, the hub adjnstably secured to said sleeve and adaptedto carr the igniter-carn and. provided with the clntc whereby the igniterfcam may be driven in operative direction and reversed in the oppo- .site direction, the igniter-cam loose on said huband driven by said clutch andprovided With the projection having the shoulder at one side, the movable eccentric having the operating-handle and suitably supported, the triplleverinounted on said eccentric and receiving motion from said igniter-c'am and imparting motionto said igniter-stern, substantially as shown and described.

In testimony whereof- I affix mysignature in presence of two witnesses.

Vansiekie, of Indanapo1is,1ndig,na foran improvement in Gas-Engines, was erroneously isued to Thomae F. Seullin and Henry C. Jordan, as 'owners of the entire interest in said Ainvention that said Letters Patent'should beve been-.iseued to the inventor, Arlea'nder A. Vansckle, Thoms F. l

Zin, and Henry CQJm'dan, jointly; said Thomas F. Scullin arid Henry C. Jordan being assiguees of two-'thirds interest only in said patent, as shownhy the record of assignments in this Ofee; and 'that the seid Letters Patent should be reed with this correction therein thai-the same may Aconform to the record of the case in the Patent Oice.
